Description: Sage Mode is the empowered state humans enter when they learn to draw natural energy inside them and blending it with their chakra. By doing so, the human creates new senjutsu chakra that allows them to enter Sage Mode. Sage Mode enhances the combat efficiency of the user by allowing them to tap into the natural force of the world that opens new techniques to the user and allows them to power up existing ones with the new senjutsu chakra. Sage Mode can be learned in two places, Mount Myōboku of the toads and Ryūchi Cave of the snakes. Learning Sage Mode at Mount Myōboku or Ryūchi Cave grants the user with a toad and snake style of Sage Mode respectively, which carries over the same advantages and disadvantages, only differing in application. So while one may be a toad sage or a snake sage, one may not be both. Only those who already possess "extreme chakra levels" can utilise natural energy to invoke senjutsu. The user's physical strength, speed, stamina, reflexes, perception and durability dramatically increase. Also, The user's ninjutsu, genjutsu, and taijutsu become substantially more powerful. And aside from gaining the ability of sensing chakra and bad emotions around them, the user can manipulate the natural energy that surrounds them in this mode, turning it into an extension of their body, which increases the reach of their attacks.

Used For: Supplementary
Element: Natural Energy
Range: Self
Duration: Until Cancelled
Hand Seals/Charge up: The user must summon the creature which would help him maintain Sage Mode. In Neru's case, she would summon Shiva.
Description: By summoning Shiva, the latter fuses with Neru. Doing so not only maximizes the Sage chakra for the user allowing them easier and faster access to sage mode, but it also allows the toad to continuously gather natural energy for the user thus eliminating the possibility of running out of natural energy during the battle.
Name: Heal Bite
Rank: Varies
Type: Ninjutsu
Used For: Utility
Element: User's Own Chakra
Range: Short
Duration: N/A
Hand Seals/Charge up: None
Description: By either letting others bite her, or biting herself, the user can suck out some of her chakra and/or let others do so. By doing so, she can heal the wounds of others or her own without needing any medical knowledge whatsoever. This ability has been shown to heal even life threatening injuries in a short period of time, and is capable of quickly energizing those the user heals; even if its herself. The amount of chakra used depends on the wounds. Simply cuts or bleeding would take chakra equivalent to that of a D rank jutsu, while severe and easily fatal wounds would use chakra equivalent to an A or S rank technique. Nevertheless, the user is not a constantly open source and merely biting the user won't cause the effects. The user has to willingly allow herself or others to benefit from her ability thus allowing the effects to take place.
